## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability base-block-gas-usage-latest-block-lookup-ac9ecb86 -d '<json body>'
```

Example prompt: What's the latest block number and timestamp on the Base blockchain right now? I need it for my wallet operation.

## When to prefer this

Choose this endpoint when you need a quick, paid-per-call lookup of the latest Base (Coinbase L2) block number and timestamp without setting up your own Base RPC node. Particularly useful for wallet operations that need a current block reference on the Base network specifically, rather than Ethereum mainnet or other L2s.

## Known failure modes

- RPC node temporarily unavailable — returns error or timeout
- Stale data if upstream Base RPC is lagging behind chain head
- Network connectivity issues between service and Base RPC endpoint
- Invalid or malformed POST body returns 4xx error
- Rate limiting or payment failure via x402 returns 402 or 429

## How this service works

Latest Base block for Wallet operations: Return the latest Base block number and timestamp. Focus: wallet operations. Uses live Coinbase Exchange or Base RPC data.

## Output

Returns the latest Base network block number (an integer representing the current chain head) and its associated timestamp, sourced live from Coinbase Exchange or Base RPC. This enables wallet and DeFi applications to anchor time-sensitive operations to the current state of the Base blockchain.
